Paypal NVP with PHP error

Question

私は自分のカートを処理するために私のウェブサイトのためにPaypalのNVPインターフェースを使って立ち上げようとしています。私はサンプルコード（here）をダウンロードし、成功していても変更なしで実行しようとしました。 エラー番号：3エラーメッセージ：URLが設定されていません！私はlocalhostと私のホストされたサイトの両方でこれを試しました。

hash_call（）は、Paypalへの呼び出しを処理する関数です。 hash_callを呼び出すコードは（）もURLを設定しますbelow.Theirコードが含まれます：

$にreturnurl =でurlencode（$のURL '/ ReviewOrder.php currencyCodeType =？' $ currencyCodeType '& paymentType ='。。。。 $ paymentType）;

$ cancelURL = urlencode（ "$ url/SetExpressCheckout.php？paymentType = $ paymentType"）;

私はcancelURLラインがオフに見て、それを修正考えた：

$ cancelURL =でurlencode（。。$ URL '？/ SetExpressCheckout.php paymentType =' $ paymentType）。

いずれも機能しませんでした。どんな助けもありがとう。私はカールで働いたことがない。
